WOOD-BURNING STOVE.

SPECIFICATION forming part of Letters Patent No. 633,720, datedSeptember 26, 1899.

Application filed December 28,1897 Serial No. 664,044. (No moclehl Tor/f/l 1071/0111, it may concern:

Be it known that I, ERNST H. HUENEFELD, a resident of Cincinnati, in thecounty of Hamilton and State of Ohio, have invented certain new anduseful Improvements in \Vood-B urning Stoves; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to to make and use the same.

My invention relates to an improvement in wood-burning stoves, and isdesigned more particularly as animprovement on the stove shown in myPatent No. 601,556, granted to me March 29, 1898.

The object of the present invention is to provide for the ready removaland replacement of the fire-pot or any part of same, so that when anypart of the fire-pot becomes worn or burned out it can be replaced bythe owner of the stove without the aid of skilled labor.

iVith this object in View myinvention consists in the parts andcombinations of parts and in the details of construction, as will bemore fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view in elevation of a stoveembodying my invention. Fig. 2 is a view in vertical section of same.Fig. 3 is a view in horizontal section on the line as 0; of Fig. 2. Fig.a is a view of the top plate of the fire-pot detached. Fig. 5 is a topview of the bottom plate, and Fig. 6 is a perspective view of thesmoke-pipe collar.

A represents the outer jacket, preferably I rectangular longitudinallyand square transversely. This jacket is preferably made of sheet metaland surrounds and contains the cylindrical fire-pot B. In my formerapplication above referred to this fire-pot is made up of a cylindricalbody with top and bottom sections rigidly fixed thereto. 1n the presentinstance this fire-pot is made up of a cylindrical body a, preferably ofsheet metal, and a removable top I) and removable bottom 0, preferablyof cast-iron, the top and bottom sections being provided each with a rimd on its inner face, adapted to fit within the adjacent open end of thebody a of the fire-pot, and thus not only prevent the ends 1 or 0 fromslipping or moving laterally on the body, but also prevents the bodyfrom collapsing at its ends and makes-the fire-pot practicallyair-tight. The top or top plate bis provided with a central fuel-openingbounded by a vertical rim or collar f, which latter projects up throughthe openingin the top of the outer jacket, and the top I) and rim f arereinforced and strengthened by the ribs g, which latter are integralwith both and form seats for the top plate of the outerjackets, and thusoper ate as spacing-blocks to hold the top plate of the jacket and thetop of the fire-pot the required distance apart. The bottom plate 0 isprovided on its lower face with ribs h, which latter are for the purposeof adding strength to the plate. The body and the top and bottom platesare removably secured together by the bolts h, passing through lugs tinthe top plate I) and down through lugs t" on the bottom plate 0. Thesebolts are preferably headed or bent at their upper ends andscrew-threaded at their lower ends for the attachment of the nuts j.Hence it will be seen that by removing the nuts the parts can beseparated for repair or removal.

Loosely seated on the lower plate 0 within the body a of the fire-pot isthe lining F. This lining fits loosely within the body and rests on thebottom plate. Hence by removing the top plate I) the lining, which ispreferably made of sheet metal, can be removed for repair or removal.

The body a of the fire-pot is provided near its bottom with an opening7;, reinforced on its inner face by the cast-metal plate 70', having anopening therein corresponding to the opening 7.; in the body a. Securedto the outer face of the body a and to the reinforcing-plate k is theflue-box I. This box is carried wholly by the fire-pot and is providedat its lower inner end with an opening registering with the opening 70in the firepot and near its upper outer end with an openingcorresponding with a similar opening in the outer jacket. From this itwill be seen that this draft-box is located within the air-space betweenthe outer jacket and fire-pot, and the air as it enters passes downwithin the box and escapes into the fire-pot near the lower end of thelatter. The fire-pot also carries near its upper rear side thesmoke-collar L.

This collar is preferably made of cast metal arrangement of the severalparts herein and projects through a corresponding opening in thejacketand is provided with the rigid or, if desired, integralspacing-blocks Z, which latter form bearings for the outer jacket atthis point.

To attach the fire-pot to the jacket, the parts of the form er areassembled as described and introduced into the jacket through the loweropen end of the latter. Screws m are then passed through the flat metalring N, resting on the top of the jacket and around the rim, a flangesurrounding the fuel-open ing in the top plate, and into screw-threadedopenings in the top plate I) of the fire-pot. I prefer, however, toemploy screw-bolts and pass them through the top plate of the tirepotand secure them by nuts 92, as shown. This construction and arrangementwould support the fire-pot; but in order to take part of the weight fromthe top of the jacket and also to hold the fire-pot in its properrelative position within the jacket I prefer to employ the braces 0.These braces 0 may be integral with the bottom 0 of the fire-pot or maybe secured thereto and are provided at their ends each with an openingfor the passage of a screw-bolt through the outer jacket. In order alsoto further brace the parts, hold them in position, and assist in takingthe weight of the fire-pot and its contained fuel, I secure the partstogether around the smokeflue and around the draft-box by screw-boltsand nuts passing through reinforcing-rings, the jacket, and thefire-pot. By removing these screw-bolts, together with the boltsconnecting the top plate and the bolts connecting the braces carried bythe lower plate, the

fire-pot and its attached parts can be withdrawn from the jacket and anyof its parts renewed or repaired. \Vith this construction thecylindrical fire-pot is slightly less in diameter than the shortestdiameter of the jacket, thus forming restricted air-space at the pointscentrally between the angles or corshown and described without departingfrom the spirit and scope of myinvention. Hence I would have itunderstood that I do not limit myself to the precise details hereinshown and described, but consider myself at liberty to make such changesand alterations as fairly fall within the spirit and scope of myinvention.

I-Iaving fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. In a stove the combination with a jacket open at its bottom, of afire-pot suspended from the top of the jacket and comprising separablebody, and top and bottom plates, and bolts depending from the top plateoutside of the body and removably supporting the bottom plate inposition against the lower end of the body.

2. In a stove, the combination with a jacket open at its bottom andprovided with a fuelopening, of a fire-pot having a fuel-openingcorresponding in position with the opening in the jacket, the saidfire-pot comprising separable body and bottom and top plates, the topplate being secured to the under side of the top of the jacket, boltsdepending from the top plate outside of the body and removablysupporting the bottom plate against thelower end of the body, and aremovable lining resting on the removable bottom of the fire-pot,substantially as set forth.

3. In a stove, the combination with a jacket open at its bottom andprovided with a fuelopening, of a fire-pot comprising separable- ERNSTH. HUENEFELD.
